A character actor may play a one-dimensional, stereotypical character, such as a "thug" character or a stereotypical gay person.
Double A double is an performer who stands in for a lead performer in scenes that might be too dangerous or too revealing for the lead actor, such as a body double or a stunt double.
Extra/Background An extra is an actor who performs in the background of a scene, in order to give the illusion that the scene is real life.
An extra or background actor usually has no speaking role, or a very brief speaking role.
